Flat battery

I havent used my landy much in the last three months or so, just turn it over once a week or so for ten minutes. Used it yesterday for a few short journeys and the battery light came on in the dash. Went to used it today and the battery was very weak. Was just wondering how much of a run it would need to charge up. Also if im not using the landy much, is it worthwhile turning it over once a week, or does this just drain the battery.
Thanks

just turning it over uses a lot of juice. take it for a short drive upto running temperature. this will allow the alternator to charge the battery more.

I suggest you whip the batt out and charge over night and monitor for voltage drop. then do the same but in the vehicle. you may have a leccy fault somewhere steeling your volts. hopefully its just the lack of running causing it and not an alternator problem.

I think i read somewhere before that it takes approx 9 miles to recharge the voltage used in starting a vehicle..and that was under normal weather conditions.
